1. How do I know my BlueSky™ Air Quality Monitor is working fine?

• There are 2 ways to verify that your BlueSky monitor is working:

  1. Look at the LED light on the bottom of the device.  When connected to Wi-Fi, it will flash once every 2 seconds.
  2. Go TSI Link™ Solutions at www.tsi.com/tsilink/. Search for the serial number of the specific BlueSky Air Quality Monitor in question. Once the monitor is isolated, look for the unit status and the last posted data point.

2. BlueSky Air Quality Monitors have only one PM sensor. How do I know when the PM sensor is not working any longer?

• The BlueSky monitor’s PM sensor status is reported to TSI Link Solutions. The user get an alert when the sensor is nearing the end of life.

3. My temperature measurements are reading higher than the actual ambient reading. Is this normal?

• Your BlueSky Air Quality Monitor temperature sensor should be within 5°F of the ambient temperature. However, if the monitor is in direct sunlight, the temperature could be off by 10°F or more. If possible, move the monitor to a shaded area, so it is not in direct sunlight. During the night hours, your BlueSky monitor should read closer to other temperature sensors.

4. My BlueSky Air Quality Monitor’s data has a warning to replace the PM sensor. What is this warning and what does it mean?

• It means that the particulate matter (PM) sensor is nearing the end of its life and should be replaced.  You can order a replacement sensor from from the TSI website (single sensor, pack of 5 sensors) and install it yourself.

5. Where do I order new BlueSky Air Quality Monitor sensors?

• The replacement sensor can be ordered from the TSI website (single sensor, pack of 5 sensors).

6. Can I buy the replacement PM sensor from Sensirion instead of TSI?

• The BlueSky Air Quality Monitor PM sensor needs to be purchased from TSI so it can be serialized and calibrated. Additionally, TSI will also include the mounting board so the PM sensor can easily be installed back into the BlueSky monitor case. 

7. My PM readings have been 0.000 mg/m³ for a long time. Is there something wrong? What do I do?

• If you can access the device, try to reset your BlueSky Air Quality Monitor with a power cycle. To complete a power cycle, unplug the power supply, wait a few minutes, and plug it back in. Then check the PM sensor status in TSI Link Solutions (see FAQ on this page “1. How do I know my BlueSky^TM air quality monitor is working fine?”). If your PM sensor data displays a status warning about the sensor reaching its end-of-life, the PM sensor will need to be replaced (see FAQ on this page “5. Where do I order new BlueSky air quality monitor sensors?”).

8. My PM readings are all reading very high. Is there something wrong? What do I do?

• Your PM sensor may need to be replaced. Check the PM sensor status, which is reported to TSI Link Solutions (see FAQ on this page “1. How do I know my BlueSky air quality monitor is working fine?”). If your PM sensor data displays a status warning about the sensor reaching its end-of-life, the PM sensor will need to be replaced (see FAQ on this page “5. Where do I order new BlueSky Air Quality Monitor sensors?”).

9. My temperature and humidity values are incorrect. What is wrong? What do I do?

• Your BlueSky Air Quality Monitor temperature sensor should be within 5°F of the ambient temperature. However, if the monitor is in direct sunlight, the temperature could be off by 10°F or more. If possible, move the monitor to a shaded area, so it is not in direct sunlight. During the night hours or when placed out of direct sunlight, your BlueSky monitor should read closer to other temperature sensors.
  
  The humidity sensor should be within 10% of the ambient relative humidity. However, if the monitor is in direct sunlight, it could cause the relative humidity to be off by more. If possible, move the monitor to a shaded area, so it is not in direct sunlight. 
  
  If you believe one or both of the sensors (temperature and/or humidity sensors) has failed, you will need to order a replacement BlueSky Air Quality Monitor from our BlueSky product page. We do not sell replacement temperature and RH sensors.

10. My BlueSky^TM air quality monitor won’t turn on. What is wrong? What do I do?

• If possible, try plugging the monitor into a power supply you know is working. If the monitor turns on using a different power supply, the original power supply has failed. BlueSky monitor power supplies are made to be used outdoors, but may occasionally fail. A replacement power supply can be ordered on the TSI website (North America-style power supply, European-style power supply, UK-style power supply).
